Application filed October a, 1910. Serial No. 589,694.

To all whom it may concern:

Be it known that I, LUDWIG CARL FLAG- oUs, a subject of the German Emperor, and formerly a resident of Stettin, Germany, but now of the borough of Manhattan, city,

county, and State of New York, have invented certain new and useful Improvements in Coke-Oven Doors, of which the following is ing device, such as the chain it. The hook My invention relates to doors for coke ovens andthe like, in which provision is a specification.

made for the introduction of a fuel-leveling device after the door has been closed.

The present invention has for its object to simplify, cheapen and render more convenient and reliable in operation, the construction' of doors of-the above-indicated character. For this purpose, I have devised a novel arrangement of parts, as will be fully described hereinafter, and particularly pointed out' in the appended claims.

Reference is to be had to the accompanying drawings in which Figure 1 is a partial front view of a lo n- ,Q'llllltlllltll. coke oven provided with hey improved door; Fig. 2 is a separate face view of the door, upon an enlarged scale, and Fig. 3 is substantially a vertical cross sec 'tion through the center of Fig. 2.

A designates the masonry or setting of the bench of coke ovens, the individual ovens A being open at the ends, horizontal or longi tudinal ovens being indicated in the draw ings. Adjacent to the open end of each oven is adapted to move vertically a door ll, held in the closed position by any Well known or 'approved device (no-t shown). When closed, this door rests upon the ground or foundation. At its upper portion. the door has an opening B through which the well known fuel-leveler Inay be introduced. During the normal operation of the oven, the opening B is closed by an anxiliary door (l pivotally suspended at C from a cross bar carried by depending links 1) which are pivoted at D to brackets B at the iippcr part of the main door B. As will be seen clearly in Fig. 3, the pivots D are to the rear of the fronflsurface or seat against which the auxiliary doorC rests when closed, so that the weight of said door and of the links D will tend to hold the door (I a ainst itssrat. The e )enin 1 is iref-- h V P erably partly surrounded by a U-shaped I'll) B thus forming a space or depression for the reception of suitable material to lute the edge of the-auxiliary door, as indicated at E. This material is of course removed when 1t is desired to open the door (I.

The auxiliary door is shown as provided with cars (l at its central portion, to form a guide for the hook l" or other cinmccting member of the, door-ln'nsting or doonopen- Fl having been engaged with the cross bar C and the luting E removed, an upward pull on the chain I will cause the auxiliary doorC and the links I) to swing into the upper position indicated by dotted lines in Fig. 3, so as to uncover the opening ll. A lnrther pull on the chain l will then raise the main door B with the auxiliary 'door (.l.

Similarly, when the main door is lmvcred,

the opening B \\ill" 1'enniin open until the said door reaches its lower position (dotted lilies in Fig. the paying out of the chain 1* is then stopped to leave the opening; ll uncovered for the introduction and removal of the fuel-leveler; finally, when this opera.- tion is completed. the chain l is paid out further to allow the auxiliary door to close, and this door is lutcd if desired. It. will be seen that. the same .device serves for moving the auxiliary door relatively to the maiir door and for operatingboth doors together.

Various modifications may be made without departing from the nature of my in vention as set forth in the ap iciuled claims.

I claim 1. The combination with :1. structure having an opening, of a movable main door adapted to close said opening, said door being itself provided with an opening, and an auxiliary door movably secured to the main door and adapted to close the opcin ing thereof, said auxiliary door being adapt ed for connection with suitable mechanism to first move the auxiliary door away from the opening in the main door and then move both doors in unison.

2. The combination with a striuturc having an opei'iing, of a movable main door adapted to close said opcnin said door being itself provided with an opening, an auxiliary door adapted to close the opening of the main door, and vertical links 'l'ulcru'med of the links being horizontal.

The combination with a structure havlng an opening, of a movable main door itself provided with an opening, an auxiliary door adapted to close the opening of the main door, and. links fulcrumed on the main door to the rear of the seat of the auxiliary door, and pivotally connected with said aux iliary door. v

1-. The combination with a' structure having an opening, of a movable main door adapted to close said opening, said door being itself provided with an opening, an auxiliary door adapted to close the opening of the main door, links fulcrumed onthe main door above the opening thereof, and a horinism for first opening zontal cross-bar connecting-the, outer ends of said links, the said auxiliary door being hungon said crossbar. V

5. The combination with a structure haw-- ing an opening, of a movable main door adapted to close said opening, said door being itself provided with an opening, an auxiliary door adapted to close the opening of the main'door, links fulcrumed on the main door, and a cross bar connecting the outer ends of said links, the central portion of said auxiliary door being provided with ears pivotally engaged with said cross bar and adapted to confine and guide the attaching member of a lifting device. l

'6. The combination with a structure havlng an opening, of a movable main door adapted to close said opening, said door being itself provided with an opening, and with a depression adjacent thereto, and an auxiliary door movably secured to the. main door and adapted to fit within said depression and to close the opening of the main door, said auxiliary door being adapted for connection with suitable operating mechaand then the main'door.

In testimony whereof, I have'signed this specification in the presence of two subscribing Witnesses.
